CAR-STOP.

Specification of Letters Patent.

Patented Oct. 8, 1918.

Application led February 7, 1917. Serial No. 147,130.

To all 'whom it may concern.'

Be it known that I, JOHN SCHUH, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Car-Stops, of which the following is a specification.

My invention relates to improvements in car stops, and has for its object the provision of improved means for checking or stoppings oars passing over a track.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invent-ion will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure l is a plan view of a car stopping or checking means embodying my invention,

Fig. 2, an enlarged transverse section of the same,

Fig. 3, a section taken online 3 3 of Fig. 2, and

Fig. 1, an enlarged detail view of an operating lever employed in the construction.

The preferred form of construction, as illustrated in the drawings, comprises two friction plates or bars 5 positioned just inside of the two rails 6 of the track and carried by slides 7 mounted to slide on the tops of cross ties 8, as shown. A double-acting bell crank lever 9 is mounted centrally on each of the ties 8 and is provided with operating arms 10 arranged to contact with cam surfaces 11 on guides 7 to force the plates 5 outwardly into frictional Contact with the wheels of a car passing over said track. Each of the double-acting bell cranks 9 is connected by means of a link 12 with a corresponding bell crank 13 positioned at the side of the track, all of the bell cranks 13 bein' connected with an operating rod 14: whic i in turn is connected with an operating lever 15. The connections between the links 12 and the bell cranks 9 and 13 are made adjustable, as indicated, so that the throw of the bell cranks may be adjusted as desired.

In use a car passing over the track is gradually checked and stopped by manipulating lever 15 which serves to force the friction plates 5 outwardly against the insides of Copies of this patent may be obtained for ve cents each,

the surfaces of the wheels of the car, thus exerting friction thereon to gradually check and stop the same. B properly adjusting the bell cranks and tlieir connections, the movements of the plates 5 may be correspondingly adjusted to exert gradually increasing resistance, if desired.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the ap ended claims.

aving described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with the rails of a railway track, of friction plates arranged between said rails to Contact with wheels thereon; double acting bell cranks positioned between said plates and arranged to force them into frictional engagement with car wheels on said rails, there being cooperating cam surfaces on said bell cranks and said friction plates adapted to effect said frictional engagement' and means for operating said bell cranks, substantially as described.

2. The combination with a track having rails and connecting ties; friction plates mounted to slide on said ties; double-acting bell cranks positioned centrally on said ties, and arranged to force said plates into frictional engagement with car wheels on the rails of said track, there being cam surfaces operatively connected With said friction plates to cooperate with said double bell cranks; a plurality of bell cranks mounted adjacent said track; links connectin said bell cranks with said double bell eran s; an operating rod connecting said bell cranks; and a lever for manipulating said operating rod, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN SCHUH.
